Answer:
Step-by-step explanation:
2×radius with pi, 28*pi=28 pi or 87.92
Answer:
87.92 in.
Step-by-step explanation:
The formula for circumference of a circle is: πd (diameter) or 2πr(radius).
π - pi
Here, only the radius (14) is shown. So we would have to use this formula: 2πr.
Now, let's just plug-in the numbers.
**3.14 is commonly used for pi.**
2πr
2 × 3.14 × 14 = 87.92
OR
We could simply double the radius, and use this formula instead: πd
πd
3.14 x 28 = 87.92
As you can see, I got the same answer either way.
Therefore, the circumference of this circle is 87.92 in.
